Hi Kevin,

I'm sorry for the slow response -- I was out of town last week and had
spotty internet access.  Li Dong, in another thread, suggested that the
use of -std=c++11 causes the bus error issue, and I am curious if it
also causes the test failure.  Could you try compiling without
-std=c++11 and seeing if LoadSaveTest/SaveArmaASCIITest still fails?  If
it still fails, can you attach the file "test_file.txt" which should be
generated in the directory you run mlpack_test in?

I am trying to get a hold of an OS X system (or get my VM running again)
so that I can dig into this more thoroughly.

Thanks,

Ryan
